` IMPRVEMENT IN WINDMILLS.

' Specication forming part of Letters Patent No. 126,955, dated May 21,1872; 'antedated May 7, 1872.

' ters of reference marked thereon.

Figure l represents a side elevation of my improved windmill, with aportion of the outer hoop ofthe wheel broken away to exhibit the innerhoop. Fig. 2 represents a face View of the Wheel with the adjusting-ringand cranks. Fig. 3 represents a portion of the wheel without theadjusting-ring and cranks.

My invention relates to the combination and arrangement of the pivotedvanes of the windwheel with a self -`regulating. mechanism, as hereinfully described.

The wheel-hub A is provided with six arms, c, to which two metal hoops,ff, are fastened. Between these hoops the wheel-vanes b, of the formshown in the drawing, are pivoted, so as' to turn upon theirlongitudinal axes, when adjusted, by the action of the regulating-hap B.The wheel-shaft U is journaled in the two boxes g g, and extends outover the tubular seat D, and may be provided with a crank, to which thevalve-rod of a pump may be connected. The central frame-piece E has acircular hole through it, into whichthe upper end ofthe tubular seat Dis fastened, and its lower end D extends down into a hollow trunk,denoted in dotted lines in Fig. l, in which it will revolve as thedirection of the windacting up' on weather-vane F will require. Twobraces, d, are employed to strengthen the uprights c', in which theregulating-nap B is hinged. The hinged rod h connects iiap B with theframe i, which is hinged at its lower end and is connected by two atliuks,j, to the yoke k, which ts loosely in the neck of the collar l,which collar revolves with the shaft C. The circular flange m (for whicha cross-bar could be arms a, where theirends are bent at right anglesand connect, respectively, with the double crank-levers o at the ends ofcrank-arms p. The crank-levers are each hinged or jour naled in lugs onthe hubs` and in holes through the central hoop f of the wheel A', inwhich hoop the inner ends of the vanes b are pivoted. This hoop is ofnearly equal diameter and concentric with the adjusting ring or wheel e.The respective arms r of the cranks o are hinged to the small cranks s,which are jour naled in the adjusting-ring e. The inner ends of thevaries b have straps of metal riveted to them, which straps are bent attheir projecting ends t, where they extend outside of the ring o andform ears for the hinge, to which the short bent link uis pivoted. Thislink has one end pivoted to the adjusting ring or wheel e, and thelatteris actuated through cranks s and o and the rods 1' and the other deviceswhich connect the adjusting-wheel e with the iiap B. The wheel or ring eis provided with four spokes and a hub, the latter being free to rotateupon the projecting end of the shaft C, to allow the necessaryadjustments of the vanes b. To the upper projecting end of the pivotedflap-beam H a rod, I, is hinged and extends down for the purpose ofadjusting the vanes b by a person upon the ground.

From the foregoing description it will be understood that the positionsof the vanes b, and consequently the degree of speed of the wheel A',will be regulated by the iiap B, which will change its positions withthe varying power of the wind acting upon it. The connections betweenthe sliding collar l and the vanes b and between the liap B and thecollar lare so arranged as to effect the abovedescribed movements of theYanes b by tHe action of the wind upon ap B and by its own gravity.

Having fully described the construction and operation of my improvedwindmill, what I claim herein, and desire to secure by Letters Patent,is-

ap B and the devices by which it actuantes In testimony hereof I havehereunto set my the sliding collar l, substantially as and for hand this7th dey of September, A. D. 1871.
